Connecting the Console to the Regulator Circuit
1. Cut the power adapter cable to remove the adapter.
You will use the connector end of the power adapter cable. If you plan to
mount the regulator and the console in the Complete System Shelter (CSS),
you will need only 9” (23 cm) of cable attached to the connector. If you plan
to mount the regulator and the console elsewhere, you may prefer a longer
cable.
2. Place one C1/CONSOLE PWR/P1 label onto the power adapter cable so the C1 side of the
label is nearest the connector end of the cable. Place a second C1/CONSOLE PWR/P1
label onto the power adapter cable so the P1 end is nearest the cut end of the cable.
3. Strip approximately 5/16” (8 mm) of insulation from the wires on the power adapter
cable and insert at P1 Power on the regulator circuit.
Insert the wire with the white stripe into the terminal labelled “WHITE.”
Insert the black wire (no stripe) into the terminal labelled “BLACK.”
4. Connect the jack at the other end of the cable to connector C1 underneath the console.
If you have mounted the console outside the CSS, you will need to route this
cable out of the CSS through the cable boot in the base of the shelter.
M AINTENANCE I NSTRUCTIONS
Ensure that the solar panel surface is free from dust and foreign matter. These
may be removed using a clean water spray, or a soft cloth and soapy water fol-
lowed by a clean water rinse. Do not use harsh chemicals on the panel surface.
Test Points
Four test points, located near the bottom edge of the regulator circuit board
facilitate use of a voltmeter to check the operation of the solar panel subsystem.
✦ Test Point 4, identified by “GND” and the symbol is GROUND.
✦ Test Point 1, identified by the SUN symbol, carries the SOLAR PANEL OUTPUT VOLT-
AGE.
✦ Test Point 3, identified by the BATTERY icon, carries the BATTERY VOLTAGE.
✦ The voltage between Test Points 2 and 3, is generated by the CHARGING CURRENT
through 1 Ohm, so the voltage in millivolts is equal to the battery charging current
in milliamps.
